Yeah, it should work. The pattern "40 0F 93 C7" can be found multiple times (!) in the file. Make sure that you only replace the one that matches the "30 8B 81 64 03 00 00 48 3B D0 40 0F 93 C7 48 8B CB 48" pattern exactly, otherwise you'll be overwriting unrelated code/data that may cause the game to crash. Also make sure that you're replacing those bytes, not adding new ones (in some hex editors the default behavior is "overwrite", while others append new bytes and you have to explicitly delete the old ones).
